Title: Improvements in or relating to shuttleless looms
IPC: D03D47/40
Filed: 1955-09-01
Abstract: 807,271. Shuttleless looms; weaving fabrics folded. DUERKOPPWERKE A. G. Sept 1, 1955 [Sept 2, 1954], No 25085/55. Class 142(2) Fabric is woven folded in two by inserting a loop of weft into one layer of the fabric, then drawing one limb of the loop out of that layer and into the other layer; loops from separate weft packages are inserted into the upper and lower layers alternately, each weft being cut after two insertions, whereby selvedges are produced as in Fig. 7 (which shows the fabric opened out flat). Weft inserters Figs. 8 and 10. Needles 8, 9 each have a horizontal notch 13 in the end, and a hook 14 on front, across which projects a loop 15 of rubber. The needles are guided by rollers 12 and are fixed in a block 4 pivoted to the periphery of a gear 5; the block also carries needles 10, 11 of an adjacent weaving mechanism. Reciprocation of the needles is effected by a crank, which causes the gear 5 to roll round an internally-toothed gear 6. Weft, supplying, Fig. 14. Presentation of the weft threads to the needles is effected by clamps 52, 52<SP>1</SP>, mounted on separate toothed rings 49, which are partially rotated one way or the other, by means of toothed sectors oscillated by Geneva mechanisms, to bring the weft threads 43<SP>1</SP>, 47<SP>1</SP> into or out of the path of the needles 8, 9; each clamp can be closed by moving a semicircular yoke (not shown) to a position concentric with the ring 49, whereby the outer jaw of the clamp is pressed against the inner jaw and kept against it as the clamp rotates with the ring 49. Picking sequence, Figs. 12 and 14. The weft thread 43<SP>1</SP> is held across the path of the needle 8 by the clamp 52, as shown, so that when the needles enter the shed, the notch in the needle 8 pushes a loop of weft from the bobbin 43 into the upper shed; when the needles emerge from the other side of the sheds, a spreader 46, Fig. 12, passes downward through recesses 16, Fig. 10, in the needles to take one limb of the weft loop from the upper needle 8 to the lower needle 9, where it snaps into the hook 14. As the needles retract, the clamp 52 opens to allow the lower needle 9. to draw the 'free limb of the weft through the lower shed. After beat-up, the weft 43<SP>1</SP> ,  which now extends from the bobbin 43 to the fell F, is lifted clear of the needle 8 by the open clamp 52 and the weft 47<SP>1</SP> is aligned with the notch of the needle 9 by the clamp 52<SP>1</SP>; the needles then insert a loop of weft into the lower shed and draw one limb of it into the upper shed. The above sequence of picks is repeated, with the difference that both wefts are now anchored in the fabric, the free ends necessary to enable one limb of each loop to be transferred to the other shed being produced by the clamps 52, 52<SP>1</SP> cutting the threads near to the bobbins 43, 47.

Title: Automatic temperature-controlled electric sadiron
IPC: D06F75/26
Filed: 1945-10-01
Abstract: 600,051. Thermal switches. McGRAW ELECTRIC CO. Oct. 1, 1945, No. 25453. Convention date, April 2. [Class 38 (v)] A thermal-switch in an electric-iron, which may be that of Specification 600,050, is adjustable by a wheel 103 which is detachably fixed to a hub 95 rotatable in an insulating-column 77, which is secured to the iron casing 51 by a plate 83, screws 85, 87 and spacers 84, 86, but is spaced from the insulating handle 61 of the iron. The handle 61 is supported by a metal rod 73 of low thermalconductivity, such as stainless steel. The thermalswitch comprises a bimetal bar 21 mounted in an aperture 19 in the sole-plate 13, and adapted on increase in temperature, to move a plunger 39 downwardly so that a spring-blade 29 separates from a spring- blade 31, movement of which is prevented by a spring-arm 47. The arm 47 is adjustable by a screw 91 threaded in a fixed bracket 53 and having lugs 101 slidable in slots in the hub 95. For setting, the wheel 103 is rotated anticlockwise so that the rod 73 engages one end of an arcuate-slot 109 therein (Fig. 2), the hub 95 is then depressed to disengage serration 107 from serrations in the wheel 103, and rotated until the contacts 30, 32 are just open. The hub is then returned by a spring 94 to re-engage the wheel 103 to which it is then secured by a nut 111. A split-plug 119 carrying an indicating-dial 115 is pressed into an opening 123 in the hub 95. The handle is attached to the casing at the rear, by a plate 67 and screws and spaces similarly to the column 77.

Title: Improvements in mortar-armament
IPC: F41A5/32
Filed: 1946-08-26
Abstract: 620,420. Guns. CLARKE, C. V. Aug. 26, 1946, No. 25533. [Class 92 (ii)] A gun of the mortar type especially intended for use on infantry support tanks, has a pivoted barrel chamber adapted to be set into motion by hydraulic power by the feeding of a round into it, the chamber rotating into alignment with the barrel and a breech-block which closes the end of the chamber and fires the round, the chamber then being returned tc its loading position. The Figure shows the barrel chamber in its loading position. A round is fed down the feed shoot 6 nose first and strikes the rubber pad 12, moving the lever 13 which opens a valve 16 to initiate the flow of oil from a supply line 16<SP>1</SP> to a line 17 supplying a piston and cylinder 18. The fluid also flows into the space 16<SP>9</SP> allowing the valve seating 16<SP>6</SP> to lift and further increase the flow. Movement of the piston 19 rotates the chamber by means of an arm 20 against the action of a spring 21 until the arm 20 impinges on a depressable stop 22 when the chamber is aligned with the bxeechblock 9 and the gun barrel 33. This stop 22 opens a valve 151 extending the oil flow to a cylinder in which a piston 26 moves to rotate the breech-block forwardly by rack gearing engaging a screw-thread on the block which is moved into engagement with the lower end of the chamber, which moves axially against the action of springs 37 into engagement with the gun barrel 33. As movement of the breechblock ceases, pressure is built up in another cylinder to move a piston 27 and a lever 31 which cocks the firing pin and then slips past it, thus firing the round. As the round leaves the gun barrel, explosion gases enter a chamber in the side of the extension, operating a lever 39 which moves the supply valve 41 to connect the supply line 41<SP>1</SP> and the line 16<SP>1</SP> to a reservoir when the spring 21 returns the chamber to its loading position. To ensure a positive return of the valve 41, a link 46 connects this valve to the arm 20. To cope with a misfire, when the chamber will be in the firing position, the mechanism associated with the valve 16 is arranged to pivot on a pin 48 with the pad 12 the lines 17 and 161 being made flexible and a lever (not shown) being provided which moves the lever 39 to operate valve 41 and connect supply lines 41<SP>1</SP> and 17 to the reservoir, when the chamber returns to the position shown and the round falls out through the hole 49. A movable shield 1<SP>1</SP> prevents a round entering the casing, when the chamber is in the firing position. An exhauster fan may be fitted to the casing at outlet 51 to draw air in at inlet 50. The casing may also be provided with cooling fins.
